Adrix and Nev, Twincasters + Nim Deathmantle + Ashnod's Altar + Pelakka Wurm + Trudge Garden

Adrix and Nev, Twincasters

Nim Deathmantle

Ashnod's Altar

Pelakka Wurm

Trudge Garden

How it works

1. Activate Ashnod's Altar by sacrificing Pelakka Wurm, adding CC.
2. When Pelakka Wurm dies, its second ability and Nim Deathmantle trigger.
3. Resolve the Pelakka Wurm trigger, causing you to draw a card.
4. Resolve the Nim Deathmantle trigger from step 2, causing you to pay 4 to return Pelakka Wurm from your graveyard to the battlefield, and attach Nim Deathmantle to it.
5. When Pelakka Wurm enters the battlefield, its first ability triggers, causing you to gain 7 life.
6. Trudge Garden triggers, causing you to pay 2 to create two 4/4 Fungus Beast creature tokens.
7. Activate Ashnod's Altar twice by sacrificing the Fungus Beasts, adding CCCC.
8. Repeat.

This intricate loop uses Ashnod's Altar as the engine to repeatedly sacrifice Pelakka Wurm, whose death triggers Nim Deathmantle to bring it right back to the battlefield while drawing you a card. Every time the Wurm re-enters, its life-gaining ability triggers Trudge Garden, which feeds your mana back into the process while a doubler like Adrix and Nev, Twincasters ensures you generate a surplus of 4/4 Fungus Beast tokens. Those extra tokens can then be fed back into Ashnod's Altar for the mana needed to keep the entire cycle spinning indefinitely.
